Abnormal Uterine Bleeding Associated with Hormonal Contraception -- American Family Physician

چکیده
Most combination OCPs contain ethinyl estradiol (20 to 50 mcg) and a synthetic progestin (e.g., norgestrel, norethindrone, levonorgestrel, desogestrel). These pills inhibit ovulation in most women. They also induce thickening of the cervical mucus, which impedes transport of sperm to the uterus. With perfect use, only 0.1 percent of women become pregnant within the first year of using a combination OCP.

متن کاملInitiating hormonal contraception.
Most women can safely begin taking hormonal birth control products immediately after an office visit, at any point in the menstrual cycle. Because hormonal contraceptives do not accelerate cervical neoplasia or interfere with cervical cytology, women who have not had a recent Papanicolaou smear can begin using hormonal contraceptives before the test is performed. After childbirth, most women ca...
